What is the best method to trigger another thread from servlet?

[valsaraj007]

Hi,

I have an old code that used running in JBoss 4.2.2.GA. The request comes to servlet and then servlet processes it which contains code which takes more time. We need to return response quickly to user and so we started a new thread to process this time taking code. Started another thread using new Thread() not seems to be better. It is a JavaEE application. So can we replace this new thread part with any feature like Asynchronous EJB? I didn't check Asynchronous EJB yet. Please advice.

Thanks!

I have done it by using asynchronous method in SLSB.

That's a good way to do it. On EE7 (so Wildfly 8+), you can use a managed executor service too.

Thank you James!

Asynchronous method worked well in case of simple asynchronous tasks. But when I used asynchronous method which inturn calls many other methods in bean and fetch and persists entity to u[date status, it thrown EntityNotFoundException intermittently. Eg: updated entity Status to new before calling async method, inside method, it fetched that entity and updated processing and then other status updates to reflect progress in entity table. This kind of things not worked well. But for jobs like sending mail asynchronously worked fine.
